Title
The /etc/resolv.conf file must not have an extended ACL. (Cat II impact)
Discussion
The resolv.conf (or equivalent) file configures the system's DNS resolver. DNS is used to resolve host names to IP addresses. If DNS configuration is modified maliciously, host name resolution may fail or return incorrect information. DNS may be used by a variety of system security functions such as time synchronization, centralized authentication, and remote system logging.
Check Content
Verify /etc/resolv.conf has no extended ACL. Check if extended permissions are disabled. Procedure: #aclget /etc/resolv.conf If extended permissions are not disabled, this is a finding.
Fix Text
Remove the extended ACL from /etc/resolv.conf file and disable extended permissions. #acledit /etc/resolv.conf
